. To all whom it may concern: i

Be itknown that I, CLIO B. YAw, a citizen -of the `United States, and resldent of Arlingtom in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Type.-`

To the above and other ends my invention` i 'consists in the features of construction, com-4 binations of devices, and arrangements of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings,

. inner' end `of Fig. 9 is a detail perspective view of certain of the paper feeding devices shown in Figs. 6-8.

Asappears from Figs. 1, 2 and 6, the main frame of the No. 11 Remington front-strike typewriting machines to one oi?A which my invention is shown as applied comprises a top plate 1 from which rise lugs 2, said lugs pro- 4viding supports for grooved guide rails 3 that cooperate through antifriction ballsl 4 with a frontbar 5 and rear bar 6 ofa carriage truck, which further includes end bars 7 connecting said front and rear bars. Shiftably connected with said truck by devices S is a platen frame or carrier comprising end bars or )lates 9 and cross rods or bars 10 and 11, said platen frame and its supporting truck constituting a traveling platen carriage. The end ,bars .9 provide bearings for a two-part shaft comprising stub ends or sections 12 and 13 on which is from Fig. 5 the right-hand shaft or section 13 bears in a bushing 15 which is threaded into the end bar 9. The platen 14 comprises an ordinary wooden core 16 and rubber sheath 17. The mounting at the left-hand end is' of ordinary` construction. At the right-hand end tile stub shaft 13 is secured in a platen head 18 which is yfixed tofthe right-hand end of the core 16 by screws 19. Thel outer reduced end portion of theihead 18 receives a line spacing ratchet wheel 20 whibh is secured t'o said head by screws 21. Mounted loosely on the platen head 1S and confined between the ratchet wheel 20 and the right-hand end of the platen is a second line spacing ratchet wheel 22 and a gear ,mounted a rotary platen 14. As appears wheel, 23, the ratchet wheel 22 and gear i wheel 23 being connected so that they will turn together as by devices comprising a pin 24. Cooperative with the ratchet wheel 20 is the usual spring mounted detent 25 and in the usual limited motion on the arm Said -bushing also provides a support for 'a regulating arm 29, said arms '28 and 29beingl confined loosely between the innenface of the end bar 9 and anut 30 screwed dn the lh@ bushing 15, as appears from'Fig. 5. y

The pawl 26 is actuated by a train of devices illustrated in Fig. 2 and conjiprising a link 31 which connects said pawl with the longer arm of a bell crank 32 which is tulcrumed at 33 on the carriage truck, the short. arm of said bell crank being connected bjj a link 34 with a crank arm 535 secured to the rear end of a rock shaft 36, said rock i shaft extending forward and terminating in y cams i et.

of the carriage.

a downwardly projecting hand piece or arm 37. The rock shaftbeai's in a housing 3S fxedto the carriage truck and is provided with a restoring spring (not shown) which is contained within said housing. Ev operating the line spacing hand piece 5:37 in the. usual way the train oit devices connecting it vwith the pawl 2G actuated and the pawl itself iscaused to cooperate with the ratchet 'wheel 20 to turn the platen through a line space distance. In the presentinstance the regulating devices are set so that this oper: tion communicates a unit of line space mo ment to the platen or a single space, as it is termed. 'lhis'actuation of the paivl 2G also automatically actiiates a supplementary pawl 39 which is rotatably mounted on the stud 27 to the left of the pawl 26 and in position' to coperate with the teeth of the ratch et wheel 22. Except under certain conditions7 however, the pawl 39 is maintained in inoperative position in respect to the ratchet wheel 22 by a wire sljJiiiig O whicli iled around the stud 27 between the andy engages at its ends with pins Aell iti/L projecting oppositely from said The tendency of said spring is con- :titty to throw or hold the pawl 59 torward away from the ratchet wheel :22, this forward movement of the pawl. being limited by the engagement of the pin 42 with the forward end of a slot 43 formed in the pawl 26, in which slot said pin is adapted to play. In orde-r to overcome the spring l0 and move the pawl 39 into operative position, trat is, intoposition in which it may cooperate to turn the ratchet wheel. 2:2. when the handle 37 is actuated. devices are provided wliich are brought into ojjieiation automatically to eliect the desired' result. Said devices comprise a bar 441 (Figs. 1.23) which is arranged forward ot the platen and extends longitudinally thereof in position to engage with the front lower side oi the Lpawl 39 during lengthwise movements The bai tir lerniinatesat its ends in forwardly inclined portions or Said bar is rio'id on a plate 413 formed with a slot 47 which rcceiif'es at ils ends headed screws 48 by which the member comprising the bar and plate fill is secured to the top plate l. The construction is such that the device comprising the bar 44 and cains 45 is always stationary and in unvarying relationship with the top plate,

Athe screws 48 coperating with the ends of the slot 47 to prevent any endwise movement ot' the slotted plate 4G even when the screws are loosened. Nith the parts positioned as in the drawings7 the pawl 39 will he inoperative but as' the carriage moves flettward said pawl will. engage with the right-hand cam 45 and will be forced rearward by said cam against the spring 4() until the said pawl is brought .into engagement with the rear face of the bar 44 by which it will be maintained in position to operatively engage with its ratchet wheel during further leftward movements of the carriage until said pawl rides forward over the letthand cam The bar 44 is so positioned that during the time it is etfective to engage said pawl the tally strip hereinafter described is opposite the printing point onthe platen.- .Atter the pawl rides down over the lett-hand cam it will become ineffective but during the return n'iovements of the carriage said pawl will again ride upon to the bar 4.4 by reason of the action ot the lettehand cani 45. It will be understood that the pawl 39 will always be effective so long as it is in engagement with the bar el. but that at all other times it will be inoperative so that act-nations of the line space handle 37 will not affect said pawl 39 so Ytar Ycausing any action on` the ratchet wheel 22 is concerned. Except for certain details the double pawl construction heretofore described is like that disclosed in the applica-- tion ot Arthur YV. Smith iled Feb. 17th, 1914:, Serial No. 819.258, and is not broadly claimed per Se by me.

To cooperate with the platen I4; in the present instance, paper teeding devices of novel construction are provided which will be described in connection with Figs. 64). Said devices comprise a series oi' set of a number ot units each composed oit a main. and sccondaigv iteed roller section and the niountiiigs thereof, cach unit being adapted to be adjusted into and out ot working position without aiiecting the other units7 which may be thrown oli and released at `will while the noi'i-wtn'liing unit remains at all times ineffective. The purpose of this construction is to throw out of use the unit which opposite the tally strip so that the tally strip may pass around the platen without at any time beingialiected by the feeding de vices that coperate with said platen.and since the tally strip in. the present, instance is so mounted that. it may be adjusted to various positions lengthwise of the platen, it is desirable that any one of the palper feeding devices may be adjustable to nonworking position at pleasure. In the present instance there are three of these units and the description of one of them will be iinderstood as applying to all.l Each unit or group of paper feeding devices comprises a main feed roller section 49 and a sccondary section 50, thesebeing mounted respectively on rods or shafts 51 and 52 which are'supported at their ends on parallel arms 56 p'ivote'd at 54 between their ends to for- ,vi'ardly-extendin arms of three-armed lever f, V:members lifwhii are pivotally mounted on ""-a-ffdi that is rigid on the platen frame. f-,SaidQrpdt56 is secured to angular brackets .257 hich are fixed by screws 58 to the bar A'aifflextend rearward therefrom and then at-an angle, the rod 56 bein sup- "po ,tdnlat the an e. 4The downward y ex- `ten "rins oft e'three-armed lever memareconnected'by draw springs 59 to 'ar.'10, the springstending constantly niaiiitainthe rollers 49.' and 50 in c0- 4, lfiori'-with the platen as in Fig. 7. The 'wardlyextending portions of the brackets c 'ljored out to permit the passage there- -gh'fof a release: rock shaft 60 which I, 't'ffitsends in theplaten frame and ided near its left-hand end with the ,slesin arm or lever 61. The'parts escribed are common to the machine'. i, i 'ftreleiismg-devices are mounted on l'60 cpmprisinghcollars 62 arranged p ced-apartftl ere being a pair of l1 mii jfifor` eac paper feedin unit. ll ris'bored-'ouQas indicate Aat 63, :fthe-rock shaft 60 and receives adjustably secure in xed relation- A' tp said shaft. Between the said screws collar is formedwith a .slot or kerf 65,

' ,I y'portion or abutment that receives 'ia' peter adjusting screw- 67 that isin register withjorin the same vertical plane 'as the ,@"s'lof Bearinlrotatably on the shaft 60 iandfonned wit 'n the lslot 65 is a releasing ",.jlever 68.V The lower arm of each lever is adapted to coperabe with the upright arm of one of the three-armed lever mem ers 55.

'45 ghe upper arm of the lever 68 passes in rear of the abutment 66 and is adapted to co- .perate with the back face thereof, as in ig. 7, or with the end of the set screw 67 when the latter is screwed in rearwardly through the abutment, as in Fig. `8. In the `present instance the left-hand ljiiiper feeding unit and the middle paper feeding unit are arranged with the levers 68 normally set as in Fig. 7, while the right-hand unit, which is opposite the tally strip devices to be hereinafter described, has its levers 68 set as in Fig. 8. With the levers 68 normally set as in Fig. 7, an actuation or rearward ush ofthe release lever 61 will rock the sha t 60 6,0 and cause the abutments 66, acting against the upper arms of the levers 68, to rdck said levers, causing the lower arms of said levers to coperate with-` their respective threearmed lever members U15, rocking said lever members on the rod 56 and causing the arms "set srews'i b which the collar' SeachA ,collar further-,comprises an up.

53 to be lowered and the feed or pressure rollers carried thereby to be`released. On

the other hand, the screwing in of the atl-- justingscrew 67 in the Fig. 8 position,

causes said screws to act individually on their respective levers 68, rocking said levers on the shaft 60, which is stationary at the time, and causingv the lower arms ,of said levers-acting against their respective threearmed levers 55, to overcome'the springs 59 and effect the release of the associate feed or pressure rollers, as in Fig. 8. It will be understood. that the throw-off of the presf 4mitting the upper arm of the lever ltolbe restored to engagement with the backfof the abutment 66 under the influence "of the springs 59 actin 'through the three-'armed levers 55. It wil be seen that the abutments 66 are in e'ect crank arms on'the r'ock shaftf60, which are4 effective to engage with and `move the levers 68 which are loose 'on said rock shaft; also that the 'screwing in of the screws 67 has the same effect as-'would a resetting of said crank arms toward theV rear with a conse uent change in the normal position of the evers 68, of which said crank arms Aare actuators; or, in another sense, couplers whereby the loose levers 68 are in effect caused to rock with the shaft 60 as though they were set or fixed thereon. It will be further noted that by the resent invention there is provided a` lura ity of alined, individual feed rolls t atare se- 'lectively discardable at will, and that with these are combined means for casting 0H the non-discarded or active feed rolls, such casting off or releasing not interfering with the discarded roll or rolls. case the discardable rolls are arranged in two lines or sets comprisin independent parallel pairs of feed rolls. e discardable rolls are indefinitely'held in disuse and the construction provides, as will hereinafter appear, for adjusting the tally carrier or roll lengthwise of the platen to bring it into reglster with a `roll or rolls which may have been discarded 0r set in disuse.

The tally strip devices proper are mounted on two parallel rods or bars 69 and 70 arranged above the platen, one directly in front of the other and secured ab their ends to the bars 9 (Figs. 1, 2, 3 and 6). The tally strip supporting frame comprises par allel upright end plates 71 and a connecting cross bar 71..i: Said plates are forked at their lower ends, the forks being provided with hub portions 7 2 which fit over the rods 69 and 70, the hubs receiving set screws by which .the plates 71are a justably secured to .said rods or bars. The construction permits Vthe plates 71 and the devices carried thereby to be set at different places lengthwise of the platen. Near their tops the plates A71 are off-set rearward and upy ward, Atheir upper ends. providing bearings fora tally deliver carrier, spool or holder comprising ,avhub 3,' a flange 74 fixed at the left-hand end of said\hub, and a projecting pinor stubshaft 75 `rigid with said hub and'saijd ange.

The free end ofthe tally strip is drawn .oi of the back of the, tally roll vand over the cross rod 71,"" thence passing downward into the control of novel tally feeding'devices .which are arranged above the platen. Said devices comprise three tally feed'or pressure rollers ar- Aranged between the end plates 71. The central roller comprises a core 82 and a rubber i sheath 83 (Fig. 6). The core 82 is slidably mounted on a'shaft 84; which passes throu h holes in the end plates 71 and extends t e full length of the laten,lbearing at its ends in journals formed shaft 84 is provided 'With a longitudinal groove 85 which is engaged by tongues turned. or bent inward from the ends of the Iore 82. The construction is such that the'pressure roller 82, 83 may be slid along the shaft 8 4 whenever a read j ustment of th etally frame 71, 71a takes place, While at the same time, through the tongue and groove connections 85, 82 the said roller is forced to turn whenever thc shaft S4 receives rotary. movements. Such movements may be communicated to the shaft by hand through a linger button 86 (Fig. 1) fixed to the right-hand end of said shaft outside the adjacent end bar 9. The shaft 84 and the central pressure roller may also be rotated automatically through con nections between said shaft and the gear wheel 23, said connections comprising a said end in the end bars 9. The

Arran roller'82, 83 and coperative therewitliis a vsecond pressure roller comprising a coiej93 and a rubber sheath 94, while forward of the central roller and also coperative therewith is a third pressure' roller comprising a core 95; and a rubber sheath 96. These two outer pressurerollers `are confined between the' jend plates 71, bein rotatabl lmounted on y herods arloosely in A"slots 98v formed horizontallyfim the Vend -:v .plates 71.

Said means comprise and 4). The ri h t-hand cam member comp rises an arm 1 0 havinga` hub 101 Kwhich ts over the rod 97 and is fixed thereto as by' a set screw. ,The arm 100 curves rearward over the shaft 84 and is provided at its rear with a curved or cam edge 102 which is adapted to coperate with the p ro'ecting V end of the rear rod 97 Said arm is r urther provided with an upward extension from the end of which projects a lateral iingerpiece or key 103. When the finger piece 103 is pusheddownward and rearward it causes the forward rod or shaft 97 to turn' and brings the cam 102 into engagement' ged at the rear of the central pressure pressure rollers away fromthe "central pres- I sure roller so as to render the vtally .feeding with the rear rod 97, said' cam acting on' said rod t0 force 1t rearward in its slotted bearing, while the re-action forces the forward rod 97 forward in its bearing. To insure a proper releasing action a similar cani member is provided at the left comprising a curved arm 104 having a lhub 104 secured to the forward rod 97 and termi-: nating at its rear in a cam similar to the' cam 102, the cam acting on the left-hand pro l, .95' "have end portions which'e` 'xte1idy upward and jecting end of the rear rod 97. The left-l hand cam member 104 is not provided with a` linger piece. As a preliminary to' adjustingthetally strip 80 its outer pressure roll- `ers are cast off from the central roller` by 4have been moved to operative position so thatan actuation of the line space handle or lever 37 will not only turn the platen through the pawl and ratchet devices 26 and 20 but will also operate automatically to vturn the tally `pressure rollers and feed tnrnthe gear wheel 23 which idler 90 turns the pinion 87, causing a rotatends to `draw the the tally strip around the platen. This last result` is accomplished by the pawl 39 act` ing on the ratchet wheel 22, causing it to through the tion of the shaft 81 and of the central pressure roller mounted thereon. The rotation ofthe central pressure roller is transmitted to the outer pressure rollers, causing the rear roller, in conjunction with the central roller, to draw the tally strip off the delivery holder and advance it downward toward the platen, while the coperation of the front roller with the central roller simultaneously tally strip upward away trom the platen at the front side thereof. It may be noted at this 4point that the operation of the line spacinghandle 37 at this time is limited toone actuation since the space bei tween the bar 44 and the teeth of the ratchet wheel 22 is so narrow that the pawl 39, after it has once been lifted by an actuating operation, is prevented from dropping downward oft is ratchet wheel.

Iii

toa` yosition where it can engage a fresh tooth This construction 1s advantageous in that it safeguards against `faulty operation of the mechanism and serves as an indication that the tally strip,- has been actuated. While the endwise relai" tionship between the pawl and ratchet mechanism 39, 22 and gears 23 and 90 Aon the one hand and the platen on the other is a constant one, the cndwise relationship between the platen and the central tally feed roller is variable, changing with the adjust- `ment of said roller, which however is constantly connected with its ratchet 23. y

The main work sheet 105 (Fig.r 2) is arranged witliimits right-hand marginal portion overlying the tally strip, said sheet being fed around the laten by coperegl between the same an the feeding devil comprising the pressure rollers 49 and 50 of which, kit will be recalled, only the centra i and left-hand units are in operation in tho present instance. The main worksheet 105 receives ink impressions from a ribbon which is. controlled by a vibrator'y carrier- 106 (Fig. 2) of ordinary construction; It is preferable that the tally stri also should receive inked impressions as istin Iished from carbon impressions, and to t is end supplementary inking devices of novel character for the tall strip are provided which I will describe in connection ywith Figs. 1, 2 and 3. Saiddevices com rise two supplementary ribbon s ools 10 arranged 1n parallelism, 'one insi e of each of theend y plates 71, said spools being mounted loosel upon a shaft 108 which extend'sthroug openings in said plates 71.. The Vspools are adapted to be connected in'alternatinto rotate with the shaft 108 through-.handy con- Asa trolled `clutch devices, certain of said clutch i devices servin also as bearings ,for the shaft 108, be1ng..interpose'd between said shaft and the supplementary ribbon spools, of which in eifectfthey are a parti'.

vthe shaft 108, said` wheel being proyided `avmg a.V

, At the u left outside the end plates 71 a. cl'tch) Wheelhub 111 which extends inward er toward4 the right through an opening in the plate 71 to the right of which' plate is mounted the ribbon spool 107, said spool being fitted over the hub 111 and secured thereto by a set screw.111. The construction permits the clutch wheel y109 and the spool 107 to rotate as one while thev plate 71, inter osed between them, prevents movement othe clutch memberand s ool lengthwise of the shaft 108. This sha bears in the hub 111 4which serves as a journal for it. The shaft may turn independently of the wheel 109 and its: ribbon spool, which devices on the other hand may also turn independently of the shaft. Cooperative with the wheel 109 is a second clutch wheel 112 provided with crown clutch teeth 113 that arel ada ted to meshwith the teeth 110. The'whee 112 is suitably fixed to the shaft l108 near` its lefthand end and is provided `with aphu-b 112 formed with two a circumferential grooves 114 and 115. Adapted to coperate with these grooves is a pivoted latch 116 pivoted vat 117 to the end ofthe cross rod 71, and' provided with a draw spring 118, which tends its pivot and maintain itengaged with one or another-of the grooves 114 and 115, de-

pending on which is in re ister therewith.V

lVhen thus engaged, endwise. movement of the'ishaft 108 is prevented, but when thelatch is lifted the shaft 108 may` be shifted endwise to bringl the clutch wheel 11.2 into engagement wit the clutch wheel 109 or to force said latch downward about iso 1o with clutch teeth 121 and a hub L22 which extends inward through the plate 71 and surrounds the ushaft' 108. The right-hand spool 107 is fitted over the inner end portion of the hub 122 and is fixed thereto by a set screw 123. The shaft 108 and the wheel 120 are relatively rotatable and in order to connect them for simultaneous rotation a clutch device or wheel 124 is fixed to the shaft 108 near its right-hand end and is formed with inwardly projecting clutch teeth 125 adapted for coperation with the teeth 121. The clutch vwheels 112 and- 124 are so arranged in respect to their associ-1 ated clutch wheels that only one of said connecting clutch wheels,` 112 and 124 can be operative at time.. Thus when the Wheel'112 is clutching theV Wheel 109 and sov connecting the left-hand ribbon spool to turn with the shaft 108 the wheel 121 is inoperative and the right-hand ribbon spool is consequently loose on the shaft. 1f the latch or detent device 116 be lifted and the shaft 108 be moved vendwise toward the left, the right-hand spool 107 will be clutched to the shaft 'by the wheel 124, while the lefthand-spooi will be freed yby reason of the disconnection of the clutch wheel 112, thus reversing the direction of the ribbon feed. The shaft 108 is a ribbon driving or power shaft which is adapted to be turned autolnatically or by hand through connections to the shaft 8l. Said connections comprise a pinion 126 which, as best appears from Fig. (-3, has a `slidable connection with the shaft 8l but is also eolnpelled at all tilnes to l'otale with said shal'l blv reason ol' a radial pin 127 |i.\'ed to said pinion and engag'ing the grooveH. the ronstruetion being such that the pinion. may be shifted endwise along [he shaft while retaining its operative coiincetion therewith. Said pinion meshes with a gear wheel 128 which surrounds and is fixed to the clutch wheel 124. Flanges or disks 120 Iixed to the sides of the gear wheel 128 enibrace 'or engage loosely with the, sides of the pinion 126 and compel the pinion and gear wheel to reinain conf stantljv' in mesh no matter what lateral shiftingmovements take place. ifor example, when the shalt 108 is moved eudwise in either direction to reverse the ribbon, one or another of the Harz-es 12H will. eonipel the pinion 126 to participate in this move` i nient, the pinion sliding along its shaft 84.

Said shaft7 it will be recalled, receives rotary movement either from the finger piece 86 or from the train of connections that are actuated from the pawl and ratchet devices 397 These rotary movements are communicated to whichever of the ribbon spools 107 is clutched to the shaft 108 at the itime. For convenience of rapidly turning the spool by hand, the train of connections between the shaft 8a and the ratchet Wheel 2 may be broken by moving said'shaft enc` wise toward the left to disconnect the pinion 87 from the pinion 90. During this movement the shaft will slide through the pinion 126, which will retain its connection with the gear wheel 128 so that if thereafter' the shaft 81 be rotated 'by the finger piece 86., said pinion will transmit motion through said gear to the ribbon spool shaft 108;A

which will be rotated to advance the ribbon, although the pawl and ratchet ribbon actuating devices .remain inactive. The sup` plenientary ribbon, indicated at 130, is-of narrow width and is adaptedto be WoundI on the spools 107, its ends being connected to said spools by spring' hooks 131, said hooks partly encircling the hubs of the spools to which they are secured at one end by screws 132, the free ends of said hooks being pointed as indicated at 133 to facilitate the piercingof the end portions of the ribbon. Between the spools the ribbon is controlled by a guide plate 134 which is slotted as indicated at 135 to receive headed screws 130 by which said guide plate is acljustably secured to a pivot plate 137 that is provided with cars 138 formed with holes which fit over`thc shaft 108 between the ribbon spools. 'lhus the guide plate is pivotally supported on the ri'bbonspool shafts. Said guide plate is formed at its side edges just below and forward of the spools with guide slots 13S) through which the ribbon passes ilrits downward course, and at its lower side the guide plate 'is formed with diagonal guide slots or turning bars 140 over which the ribbon passes and by which it is directed inward at right angles in a horizontal direetion and so as to be opposite the printing' line on the platen', this horizontal portion of the ribbon between the .turning bars 140 ibeing the printing portion thereof. The guide plate 131 between the turning' bars and above the printing portion of thev ribbon is eut away,A as indicatedat lfl'l. leaving a large open space. It will be understood that when the part-s are set as in Fig. l7 [he lel'tfhand ribbon spool will be turned lo wind the ribbon thereon, the ribbon at the saine tinie being drawn off the right'liand .spool and the horizontal printing' portion of the ribbon advancing toward the. left roln the righthand turning bar to the left-hand turning bar. This printing portion oll -lhe Vribbon is interposed between the work sheet 105 and the tally strip 80 so that when the right-hand side of the main work sheet receives type impressions through the main ribbon controlled by the `carrier y 106, the `tally strip Wil]- simultaneously receive imprints through the auxiliary ribbon 130. B reason of the pivotal mounting of the guite plate 134 it may be swung up to carry the anni' :lary ribbon 'ay from. the platen and leave the iront O or. printing face `thereof fully exposed. The uppery edge of the plate 13,4 is beveledlor sharpened, as indicated at 142, to provide asevering device for the tally strip which Tis led upward between the forward feeding 5 yroll and/the central feeding roll' through the` space or slotway formed between. the shaft.108 and the back ot' the upper portion of the plate 134. Leaf springs 143 pivotally secured on the cross rod '71a outside 2O the plate 7l extend forward and cooperate at their free ends with the outer flanges ot they auxiliary ribbon spools, exerting sutileient-'pressure on said spools to prevent un- ,.wduefturiiing movements thereo said leali 5 springs thus serving as brakes. With the parts constructed and arranged asdescrib'ed, when the tally strip is at the right of the printing point the main sheet only` will` receive type impressions, and-an O actuation of the line space handle will serve only to advance the main sheet, the tally strip and auxiliary or carriage carried ribbonffeeding devices remaining uiiali'eeted. .'When, however, in the' course ot the left- 5 ward movement of the carriage the tally stripfis brought opposite the printing point, an actuation of the usual printing instrulmentalities will cause type impressions to be made von the main sheet and duplicated 0 on` the tally strip, and kwhen thereafter the line sliiacing handle 37 is operated, it will not only advance the main sheet a unit ot .liuc space distance but will automatically advance the. tally strip to the same extent andwill simultaneously cause a, feeding movement of the auxiliary ribbon.

The ribbon mechanism 79er Se is not claimed. herein asfit :is the subject ot a divi-- sional application Serial No. 102,643, filed 0 June 9, 1.916.
